Built new PC, everything turns on, but when plugged into HDMI, no display

[Funderful]

Hello!
I quite literally just built my new PC in the Node 202, but with no GPU (I'm getting it later). The cable management is the hardest thing I've ever done, but after finishing, I plug it into my tv (via HDMI on my motherboard), but I see no display. Not even a signal is detected. I've tried multiple HDMI cables and ports that work fine otherwise, but it doesn't work with this. I'm going to open it up and reroute everything and try a new monitor after school, but can anyone help?

Hi, Try using a monitor for installing Windows and the graphics driver. Then, you can use the tv.
